Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: Phase 1 Study to Evaluate the Safety and Immunogenicity of the Western Equine Encephalitis (WEE) Vaccine, Inactivated, TSI-GSD 210, Lot 3-1-92, In Healthy Adults
Brief Summary: This study is designed to determine the safety and immunogenicity of WEE Vaccine Lot number 3-1-92.
Detailed Summary:
Study Objectives:
Primary: To assess safety of the Western Equine Encephalitis (WEE) Vaccine, Inactivated, TSI-GSD 210, lot 3-1-92.
Secondary: To evaluate immunogenicity of the Western Equine Encephalitis (WEE) Vaccine, Inactivated, TSI-GSD 210, lot 3-1-92.
Sponsor: U.S. Army Medical Research and Materiel Command
Current Primary Outcome: Subjects Reporting Adverse Events by Vaccination and Sex [ Time Frame: 28 days following each vaccination ]
Original Primary Outcome: Safety [ Time Frame: Through 28 days post vaccination ]
Current Secondary Outcome: Immunogenicity [ Time Frame: Baseline and multiple dates throughout study ]
The primary endpoint used to measure immunogeniciyt of the WEE vaccine, the 80% plaque-reduction neautralization titer (PRNT 80), will be evaluated for subjects in the per protocol population.
The secondary endpoint will be GMT, with 95% CI, of the PRNT 80 for WEE-specific antibodies at each scheduled timepoint.
Original Secondary Outcome: Same as current
